JOURNAL HOUSING FOR AXLEb OF LOGOMOTIVES AND RAILWAY CARS Filed July 11,1930- FIGLI.

Patented May 23, 1933 UNrrEn STATES PATENT ortica CHARLES W. TODD, FSGHENEOTADY, NEW YORK Application filed July 11, 1930. Serial No.467,225.

The present invention relates to appliances known as journal boxes orhousings used in connection with axle journals for locomotives andrailway cars.

55 The object of this invention is to provide a structure whereby thejournal housing will be adaptable for easy removal from and replacementupon the journal and supporting frame, and to permit inspection andchange ilo of parts when found necessary, and means for securing thehousing when in use, against relative movement transversely of thevehicle and accidental disengagement of the housingfrom the frame. Theinvention is 1.5 particularly designed for such housings as 265,386, nowPatent No. 1,797,361, granted Mar. 211, 1981. However in no sense 1s theinvention limited to any particular type of anti-friction means and inthe embodiment described in the present case, a type gener- 325 allyknown in the art is employed.

Other objects and advantages of this invention, relating to theparticular arrangement and construction of the several parts,

p will become apparent as the following dei tailed description proceeds.i

In referring to the drawing illustrating the invention, the scopewhereof is defined by the appended claims:

Figure l is a vertical side elevation of the journal housing disposedwithin the frame pedestal; Fig. 2 is an end view of Fig. 1 partly insection; Fig. 3 is a fragmental plan view of Fig. l; Fig. 4 is a partialvertical lo side elevation ofthe housing and frame, em-

bodying a modification of the appliance shown in Figs. l, 2 and 3; Fig.5 is an end view of Fig. 4l partly in section on the line V-V of Fig.il; and, Fig.y 6 is an isometric view of the combined shoe and lockingdevice of the modification.

In the practice of the invention, referring descriptively to an approvedembodiment thereof, which is herein exemplified, like 5' parts beingdesignated by like characters,

it is understood that the axle 1, is provided with a journal la, at eachof its ends.

While the invention is designed for use in connection with axles havingeollarless ournals, it is to be noted, at the outset, that there 55, maybe modifications of other details in va rious instances, as for example,various designs of the frame pedestals with appropriate differences,will be employed, depending upon whether the invention is to be employedin connection with a locomotive, a passenger or a freight car, or othervehicle. Furthermore, where the invention is employed either on standardequipment or old equipment for replacement, not only will the framepedestal be suitably designed, but the journal housing'will likewise besuitably designed to accommodate it for use in such equipment. While inthe embodiment illustrated in the drawing the pedestals are formedintegrally with the frame, it is also contemplated to employ theinvention in connection with frame pedestals of the detachable type.Such further modifications of minor details as may be necessary, will bewell within the province of the mechanical skill of those versed in theart.

In the present case, two embodiments of the invention are illustrated inthe accompanying drawing. In Figs. 1, 2 and 3, 80 the pedestal 3a forthe journal housing 2, made integral with the frame 3, is a loadsupporting member, and is designed to bear on the housing 2. In Figs. 4and 5 (illustrating the modification) the pedestal 3a is designed tobear on a shoe 9 (Fig. 6), which is disposed beneath the frame and whichin turn vbears on the housing. In these embodiments of the invention asaforesaid, the vaxle 1, is provided with collarless journals 1a, whichco offer no obstruction to the movement of the journal bearings andhousings longitudinally over the axles. The frame pedestal 3a isprovided with an extended lower portion 3b which allows a clearancespace 6 between 95 its inner sides and the housing, permitting arelative vertical movement, whereby the pedestal may be jacked up awayfrom the axle ournal in order to remove the housing or replace it uponthe journal. The positive locking bolt 10, shown in Figs. 1, 2 and 3, isalso vlitted with a clearance space, and the shoe 9 is allowed arevolving or vertical movement with the housing 2 when the frameseparates from the housing. rlhe horizontal movement of the housing` 2upon raising the trame pedestal for the purpose of removal orreplacement of said housing, is dependent upon removal of the lockingbolt 10, and in the modification, the supporting of the shoe verticallysufficiently to disengage the tongue on the housing (Figs. l and Thecollarless jo-urnal 1ct, is .reduced in diameter relative to the body ofthe axle 1. rlhe ournal housing 2, contains anv anti-friotion bearingmechanism, not shown, but which may be similar to that shown in myhereinbeifore mentioned copending application and the exterior diameterof the housing is made of slightly less diameter than the inner sides ofthe frame pedestal 3e, thus permitting the housing 2 to movelongitudinally on the axle journal 1a for insertion upon or removal fromthe same. The frame pedestal 3a surrounds the housing 2 on its top andsides and provides an opening 5 between its lower. portions 3?), whichextend inwardly so that the opening 5 is of less width than thehorizontal exterior dimension Aot the housing 2, but of greater widththan the exterior dimension of the axle journal la. Between the housing2 and the extended lower portion 3b, of the frame pedestal 3a is thesaid space 6 provided to permit the relative vertical movement, wherebythe frame pedestal 3a may be jacked up for removal et the housing 2horizontally from or for replace ment of the same upon the aille ournal1a. Alifter the housing 2 is removed, the axle 1 f ma be removed fromthe trame 3 b assin' D the journal 1o vertically through the opening 5.

It is important that the housing be held against trans erse movementrelatiif'e to the locomotive or car when in use, and in the presentinstance, this is accomplishedby cooperating tongue and groove members,tongue 7, (Figs. 143) being formed on top ot the housing 2, laterallythereof, and groove 8' being 'formed laterally in the interior of thetop Wall of the trame pedestal 3o. Correspondingly,in the modification,4;6) the tongue 141 is formed on the top oit the housing 2, laterallythereof, groove 15 is f' formed in the bottom ci' the'shoe 9, groove 22is formed in the upper side ot the shoe, and tongue 21, formed on theinterior of the top wall oit' the tramo pedestal. 3a, the tongues andgrooves cooperating with each other to prevent transverse movement ofthe housing relative to the locomotive or car.

The lugs 18 (Figs. 1-3) cast integral with the housing 2, lug 12 castintegral with the 'frame pedestal 3a and the bolt 10 disposed throughchannels in said lugs and secured by an enlarged head 4, and the splitkey 11, form a positive lock, preventing accidental disengagement of thejournal housing 2, from the frame pedestal 3a, Correspondingly, the shoe9 is provided with a locking element 9a, (Figs. 4 6) cooperating withthe lugs 18 on the frame and the pin 17, to secure the housing' againstaccidental disengagement when the modilied form of the invention isused. lt will be apparent that while the housing of the embodiment shownin Figs. 1 to 8 inclusive, is locked against vertical movement relativeto the frame, so as to prevent accidental transverse movement anddisengagement, the housingoi the modilied form of the device illustratedin Figs. 4l to 6 inclusive, is not so locked, and may upon passing overuneven or rough track have a limited vertical movement with relation tothe frame and move out of engagement with the top of the pedestal. Underthese conditions, however, the shoe 9, by reason of its locking element9a, will follow the housing, swinging on the pin 17, and preventtransverse disengaging movement of the housing. rllhe pin with thelocking element 9a Will serve as a guide tor the shoe in bringing theparts back together, and the shoe, asy aforesaid, will secure thehousing against accidental disengagement.

The locking element 9a is formed with an open end 16, to allow freemovement with respect to the pin 17, which is secured in or castintegral with the lugs 18 on the trame pedestal 3a.

The open end 16 of the locking element 9a permits the shoe 9 to beapplied to the trame pedestal 3a, through the opening 19, and thelocking element passed over the pin 17, prior to the insertion of thehousing 2, upon the axle journal 1a. A lever armv20 is provided on theshoe 9 above the locking element 9a by which the shoe may be revolvedabout the pin 17, to vertically hold the groove 22 against the tongue 21and provide clearance for the housing 2 for its insertion upon orremoval from the axle journal 1a.
